I have been experiencing an error with tksurfer. It occurs when I am trying to generate an occipital patch, following these instructions: http://surfer.nmr.mgh.harvard.edu/fswiki/FreeSurferOccipitalFlattenedPatch

I open a surface using: tksurfer <SUBJ> lh inflated -curv lh.curv

Following the steps, when I click the surface and press the "Fill Uncut Area" button, tksurfer crashes with the following error:

tksurfer.bin: tnl/t_vertex.c:407: update_input_ptrs: Assertion `a[j].inputstride == vptr->stride' failed.

I have also experienced this problem zooming out on a specific surface patch.

I have seen this problem in different forms on the mailing list, but have not seen any solutions or workarounds:
